Be'itlmown that L EDWARD LARSON, conactor, subject of the King of Sweden, residing at Lerdala, Sweden, have invented certain new and useful Improvements in Safety Devices forFirearms, of'which the following is a specification.

armsand has for object to procure a more simple and more reliable device of that kind than has heretofore been proposed.

The invention is principally characterized by two locking members, preferably arranged on opposite sides of the frame, where by both thelocking members independently of each other lock the trigger in its safetyposition and are automatically and inde pendently of each other moved from this position when the arm is placed in the hands in position to be fired.

Two embodiments of the invention are 3 shown in the accompanying drawing, whereinFigure 1 is an elevational view of a gun frame to which my invention has been applied and Fig. 2 a similar view of another embodiment. Fig. 3 shows a detail.

in Withrespect of the embodiment shown in Fig. 1 ldenotes the usual trigger, which is v .pivoted to a pin 2. The two locking memfl bers consist, in conformity with the embodiment shown, of twolevers 3, 4 and 5, 6 5 [whereof one3, .4 is arranged on the upper side. of the frame and is formed as a bellcrank lever, the one arm 3 of which looks the trigger, while the other lever 5, 6 is arranged onthe underside of the frame and in the same way locks the trigger. The arms 4,6 intended to be operated by hand pref-, I 4.0,,

Hereby the trigger will b unlocked in order that the same may be operated in y the usual way in firing. Firstly the locking Y EnwAnnLAnson, E LERDALA, SWEDEN.

member 5, 6 is operated,whereby the arm unlocks the trigger,-'whereupon the locking willbe placed directly'fabove a recess 7 in the trigger so as to allow the free movement of the latter. 1

According to the second embodiment the member 3, 4 is divided into two or several parts -4 and 4, movably connected with each Said movable connection may be of convenient kind. I have, however, found that the arrangement is performed in the best way by placing a pivot 8 on one of the parts, while the other part is provided with a slot or such like 9, being oblong for the purpose mentioned hereinafter.

The free end of the arm 4 is pivoted to a pin 10 and the locking member is in usual way pivoted to a pin 11. It is obvious that the part extending outside the frame is moved insuch a way in operating the arm 4 that the arm 3 of the locking member unlocks the safety-device, whereby the slot 9, as mentioned above, must be oblong because the distance between the points 10 land 11, counted along the parts 4, 4 'of the arm, is extended.

Said arrangement is provided for the purpose that the part of the locking member which extends outside the frame may be arbitrarily moved backward from the pivot of the said member. 7

It is to be observed that if the arm 4, 4" is situated in the vertical middle plane of the frame, then must the same be provided usual screw 12 to pass.

The last described modification works in the same way as the first embodiment. X

It must further be observed, that the other arm 3 of the locking member 3, 4 is placed between two safety-levers 13, said levers being pivoted on the pin 11. The arm 3 looks V the triggers 1 and 1 (Fig. 3), while the levers 13 look the sears 14. The arm 3 can be moved into the safety-position independent of the locking levers 13 and remain in said position. The arm 3 and the locking levers 13 are, however, at the same time arranged in such a way as to be simultaneously 105 1O 7 independent of each other, meai s for re-.- leasmg said locking members from said trigdmoved from theirsafety-position. The arm 3 is for that purpose provided with a catcher 7 02 s pat n In ay e qbta fid vf 15 which by the movement of the arm from the safety position unlocks the seals 'I claim: 7 T y 1.
